1. Description of Business and Nature of Operations

Wheaton Precious Metals Corp. is a precious metal streaming company which generates its revenue primarily from the sale of precious metals (gold, silver and palladium) and cobalt. Wheaton Precious Metals Corp. ("Wheaton" or the "Company"), which is the ultimate parent company of its consolidated group, is incorporated and domiciled in Canada, and its principal place of business is at Suite 3500 - 1021 West Hastings Street, Vancouver, British Columbia, V6E 0C3. The Company trades on the Toronto Stock Exchange ("TSX"), the New York Stock Exchange ("NYSE") and the London Stock Exchange ("LSE") under the symbol WPM.

As of September 30, 2025, the Company has entered into 40 long-term agreements¹ (32 of which are precious metal purchase agreements, or "PMPAs", three of which are early deposit PMPAs, and five of which are royalty agreements), with 33 different mining companies, related to precious metals and cobalt relating to 22 mining assets which are currently operating, 22 of which are at various stages of development and 2 which have been placed into care and maintenance or have been closed, located in 18 countries. Pursuant to the PMPAs, Wheaton acquires metal production from the counterparties for an initial upfront payment plus an additional cash payment for each ounce or pound delivered which is either a fixed price or fixed percentage of the market price by contract, generally at or below the prevailing market price.1

The condensed interim consolidated financial statements of the Company for the three and nine months ended September 30, 2025 ("Interim Financial Statements") were authorized for issue as of November 6, 2025 in accordance with a resolution of the Board of Directors.

2. Basis of Presentation and Statement of Compliance

These Interim Financial Statements have been prepared on a historical cost basis, except for certain financial instruments which have been measured at fair value as at the relevant balance sheet date. The Interim Financial Statements are presented in United States ("US") dollars, which is the Company's functional currency, and all values are rounded to the nearest thousand US dollars (US\$ 000's) unless otherwise noted. References to "Cdn\$" refer to Canadian dollars.

These Interim Financial Statements have been prepared in accordance with IAS 34, Interim Financial Reporting ("IAS 34") as issued by the International Accounting Standards Board ("IASB"). The accounting policies applied in these Interim Financial Statements are based on IFRS Accounting Standards as issued by the IASB ("IFRS") and have been prepared using the same accounting policies and methods of application as disclosed in Note 3 to the audited consolidated financial statements for the year ended December 31, 2024 and were consistently applied to all the periods presented unless otherwise stated below. These Interim Financial Statements do not include all the information and note disclosures required by IFRS for annual consolidated financial statements and therefore should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2024.

The preparation of financial statements in accordance with IAS 34 requires the use of certain accounting estimates. It also requires management to exercise judgment in applying the Company's accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the financial statements, are disclosed in Note 4.

In the opinion of management, all adjustments (including normal recurring adjustments) necessary to present fairly the financial position at September 30, 2025 and the results of operations and cash flows for all periods presented have been made. The interim results are not necessarily indicative of results for a full year.

3. Material Accounting Policy Information

3.1. New Accounting Standards Effective in 2025

Amendment to IAS 21 - Lack of Exchangeability

Effective January 1, 2025, the Company adopted the Amendment to IAS 21 - Lack of Exchangeability. The amendments contain guidance to specify when a currency is exchangeable and how to determine the exchange rate when it is not, as well as associated disclosure requirements when it is concluded a currency is not exchangeable. The adoption of this amendment had no impact on the condensed interim consolidated financial statements.

1 Minto has been removed from the mine count due to Minto Metals Corp. being placed in receivership.

Three and Nine Months Ended September 30, 2025 (US Dollars)

4. Key Sources of Estimation Uncertainty and Critical Accounting Judgments

The preparation of the Company's Interim Financial Statements requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities and contingent liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period. Estimates and assumptions are continuously evaluated and are based on management's experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. However, actual outcomes can differ from these estimates.

Information about significant areas of estimation uncertainty and judgments made by management in preparing the Interim Financial Statements are unchanged from those disclosed in Note 4 to the audited consolidated financial statements for the year ended December 31, 2024.

5. Financial Instruments

5.1. Capital Risk Management

The Company manages its capital to ensure that it will be able to continue as a going concern and satisfy its outstanding funding commitments while maintaining a high degree of financial flexibility to consummate new streaming investments.

The capital structure of the Company consists of debt (Note 16) and equity attributable to common shareholders, comprising of issued capital (Note 17), accumulated reserves (Note 18) and retained earnings.

The Company is not subject to any externally imposed capital requirements with the exception of complying with the financial covenant under its sustainability-linked revolving credit facility requiring a capitalization ratio of <= 0.60:1 (Note 16).

The Company is in compliance with the debt covenant at September 30, 2025, as described in Note 16.1.

5.2. Categories of Financial Assets and Liabilities

Trade receivables from sales of cobalt and other receivables are non-interest bearing and are stated at amortized cost, which approximate fair values due to the short terms to maturity. Where necessary, the other receivables are reported net of allowances for uncollectable amounts. The refundable deposit on the 777 PMPA, which requires a single principal payment at maturity, is carried at amortized cost, which approximates its fair value. All other financial assets are reported at fair value. Fair value adjustments on financial assets are reflected as a component of net earnings with the exception of fair value adjustments associated with the Company's long-term investments in common shares held. As these longterm investments are held for strategic purposes and not for trading, the Company has made a one time, irrevocable election to reflect the fair value adjustments associated with these investments as a component of Other Comprehensive Income ("OCI"). Financial liabilities are reported at amortized cost using the effective interest method, which approximate fair values due to the short terms to maturity. The following table summarizes the classification of the Company's financial assets and liabilities:

1) FVTNE refers to Fair Value Through Net Earnings, FVTOCI refers to Fair Value Through Other Comprehensive Income.

5.3. Credit Risk

Credit risk is the risk that the counterparty to a financial instrument will cause a financial loss for the Company by failing to discharge its obligations. To mitigate exposure to credit risk on financial assets, the Company has established policies to limit the concentration of credit risk, to ensure counterparties demonstrate minimum acceptable credit worthiness and to ensure liquidity of available funds.

The Company monitors its financial assets and does not have a significant concentration of credit risk. The Company invests surplus cash in bank accounts and short-term money market instruments. Finally, counterparties used to sell precious metals are established organizations with minimum acceptable credit worthiness and the balance of trade receivables on these sales in the ordinary course of business is not significant. Therefore, credit risk associated with trade receivables at September 30, 2025 is considered to be negligible.

Three and Nine Months Ended September 30, 2025 (US Dollars)

The Company's maximum exposure to credit risk related to its financial assets is as follows:

5.4. Liquidity Risk

The Company has in place a rigorous planning and budgeting process to help determine the funds required to support the Company's normal operating requirements on an ongoing basis and its expansionary plans. The Company ensures that there are sufficient committed loan facilities to meet its short-term business requirements, taking into account its anticipated cash flows from operations and its holdings of cash and cash equivalents. As at September 30, 2025, the Company had cash and cash equivalents of \$1.2 billion (December 31, 2024 - \$818 million) and working capital of \$1.1 billion (December 31, 2024 - \$799 million).

The Company holds equity investments of several companies (Note 15) with a combined market value at September 30, 2025 of \$264 million (December 31, 2024 - \$99 million). The daily exchange traded volume of these shares, including the shares underlying the warrants, may not be sufficient for the Company to liquidate its position in a short period of time without potentially affecting the market value of the shares. These shares and warrants are held for strategic purposes and are considered long-term investments and therefore, as part of the Company's planning, budgeting and liquidity analysis process, these investments are not relied upon to provide operational liquidity.

The following table summarizes the timing associated with the Company's remaining contractual payments relating to its financial liabilities and performance share units liability. The table reflects the undiscounted cash flows of financial liabilities based on the earliest date on which the Company can be required to pay (assuming that the Company is in compliance with all of its obligations). The table includes both interest and principal cash flows, where applicable.

5.6. Interest Rate Risk

The Company is exposed to interest rate risk on its outstanding borrowings and short-term investments. Presently, the Company has no outstanding borrowings, and historically all borrowings have been at floating interest rates. The Company monitors its exposure to interest rates and has not entered into any derivative contracts to manage this risk. During the three and nine months ended September 30, 2025 the weighted average interest rate earned on its

Three and Nine Months Ended September 30, 2025 (US Dollars)

cash deposits in interest bearing accounts was 4.2%, as compared to 5.2% in the comparable periods of the prior year.

During the three and nine months ended September 30, 2025 and 2024, a fluctuation in interest rates of 100 basis points (1 percent) would not have impacted the amount of interest expensed by the Company.

During the three and nine months ended September 30, 2025 and 2024, a fluctuation in interest rates of 100 basis points (1 percent) would have impacted the amount of interest earned by approximately \$2 million and \$6 million, respectively, as compared to \$1 million and \$3 million during the comparable periods of the prior year.

5.7. Other Price Risk

The Company is exposed to equity price risk as a result of holding long-term investments in common shares of various companies. The Company does not actively trade these investments.

If equity prices had been 10% higher or lower at the respective balance sheet date, other comprehensive income for the three and nine months ended September 30, 2025 and 2024 would have increased/decreased by approximately \$26 million and \$10 million respectively, as a result of changes in the fair value of common shares held.

5.8. Fair Value Estimation

The Company classifies its fair value measurements within a fair value hierarchy, which reflects the significance of the inputs used in making the measurements as defined in IFRS 13 – Fair Value Measurements ("IFRS 13").

Level 1 - Unadjusted quoted prices at the measurement date for identical assets or liabilities in active markets.

Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 - Unobservable inputs which are supported by little or no market activity.

The following table sets forth the Company's financial assets and liabilities measured at fair value by level within the fair value hierarchy. As required by IFRS 13, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

When balances are outstanding, the Company's bank debt (Note 16.1) is reported at amortized cost using the effective interest method.

5.8.1. Valuation Techniques for Level 2 Assets

Accounts Receivable Arising from Sales of Metal Concentrates

The Company's trade receivables from provisional concentrate sales are valued based on forward price of silver to the expected date of final settlement (Note 6). As such, these receivables and/or liabilities are classified within Level 2 of the fair value hierarchy.

Long-Term Investments in Warrants Held

The fair value of the Company's long-term investments in warrants held that are not traded in an active market are determined using a Black-Scholes model based on assumptions including risk-free interest rate, expected dividend yield, expected volatility and expected warrant life which are supported by observable current market conditions and as such are classified within Level 2 of the fair value hierarchy. The use of reasonably possible alternative assumptions would not significantly affect the Company's results.

Gold, Silver and Palladium Credit Sales

Under certain PMPAs, precious metal is acquired from the mine operator in the form of precious metal credits, which is then sold through bullion banks. Revenue from precious metal credit sales is recognized at the time of the sale of such credits, which is also the date that control of the precious metal is transferred to the customer.

Concentrate Sales

Under certain PMPAs, silver is acquired from the mine operator in concentrate form, which is then sold under the terms of the concentrate sales contracts to third-party smelters or traders. Where the Company acquires precious metal in concentrate form, final precious metal prices are set on a specified future quotational period (the "Quotational Period") pursuant to the concentrate sales contracts with third-party smelters, typically one to three months after the shipment date, based on market prices for precious metal. The contracts, in general, provide for a provisional payment based upon provisional assays and quoted gold and silver prices. Final settlement is based upon the average applicable price for the Quotational Period applied to the actual number of precious metal ounces recovered calculated using confirmed smelter weights and settlement assays. Revenues and the associated cost of sales are recorded on a gross basis under these contracts at the time title passes to the customer, which is also the date that control of the precious metal is transferred to the customer. The Company has concluded that the adjustments relating to the final assay results for the quantity of concentrate sold are not significant and do not constrain the recognition of revenue.

Cobalt Sales

The Company has entered into an offtake agreement under which all cobalt is sold to a third-party offtaker. Revenue from the cobalt sale is recognized at the time of the delivery, which is also the date that control of the cobalt is transferred to the offtaker.

The value allocated to reserves is classified as depletable upon a mining operation achieving commercial production and is depleted on a unit-of-production basis over the estimated recoverable proven and probable reserves at the mine. The value associated with resources and exploration potential is allocated at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category, generally as a result of the conversion of resources or exploration potential into reserves.

Three and Nine Months Ended September 30, 2025 (US Dollars)

Significant acquisitions, amendments and disposals of mineral stream interests (if any) in the nine months ended September 30, 2025 are outlined below. The percentage of payable production and other key PMPA terms for all mineral stream interests are described in Note 25.

Amendment to the Blackwater PMPA

On March 7, 2025, the Company amended its PMPA (the "Blackwater Silver PMPA") with Artemis Gold Inc. ("Artemis") in respect of silver production from the Blackwater project located in British Columbia in Canada (the "Blackwater Project"). Under the Blackwater Silver PMPA, Wheaton will acquire an amount of silver equal to 50% of the payable silver until 17.8 million ounces have been delivered and 33% of payable silver thereafter for the life of the mine.

As a result of the amendment, the amount of payable silver will be based on a multiple ranging from 5.07 to 5.17 of the number of ounces of gold produced, rather than being based on a fixed silver recovery factor. The ratio is currently 5.17. Once 17.8 million ounces of silver have been delivered, the determination of payable silver will revert to being based on a fixed silver recovery factor, consistent with the previous terms of the Blackwater Silver PMPA. On March 10, 2025, the Company paid Artemis \$30 million in connection with this amendment.

Amendment to the Kudz Ze Kayah PMPA

On October 8, 2025, the Company amended its PMPA with BMC Minerals Ltd. ("BMC") in respect of the Kudz Ze Kayah ("KZK") project located in Yukon, Canada, with the amendment including the elimination of BMC Minerals' one-time option to repurchase 50% of the stream for a period of 30 days after June 22, 2026 and the Company's right to repayment on certain conditions being met. In connection with the amendment, the Company advanced an additional upfront deposit of \$2.5 million to BMC at the time of execution and has committed to advance an additional \$15 million deposit on KZK achieving certain permitting milestones.

Partial Disposition of the Cangrejos PMPA

On May 16, 2023, the Company entered into a PMPA (the "Cangrejos PMPA") with Lumina Gold Corp. ("Lumina") in respect of its 100% owned Cangrejos gold-copper project located in El Oro Province, Ecuador. Under the terms of the agreement, Wheaton was to purchase 6.6% of the payable gold production until 700,000 ounces of gold have been delivered, at which point the stream would be reduced to 4.4% of the payable gold production for the life of the mine.

On June 23, 2025, CMOC Singapore Pte. Ltd., a Singapore entity and a subsidiary of CMOC Group Limited (collectively "CMOC") announced that it had completed its previously disclosed acquisition of Lumina. As a result of this change of control, on September 16, 2025, CMOC exercised the option to acquire 33% of the stream under the Cangrejos PMPA in exchange for a cash payment in the amount of \$102 million, resulting in a gain on the partial disposal of the Cangrejos PMPA in the amount of \$86 million, calculated as follows:

(in thousands)
Proceeds received on 33% buyback of Cangrejos \$
101,730
Less: 33% carrying value (16,006)
Gain on partial disposal of the Cangrejos PMPA \$
85,724

In connection with the exercise of the option, the Company's attributable gold production has been modified such that the Company will purchase an amount of gold equal to 4.4% (previously 6.6%) of the payable gold production until the Company has received 469,000 ounces of gold under the Cangrejos PMPA, dropping to 2.9% (previously 4.4%) of the payable gold production for the life of the mine.

13. Early Deposit Mineral Stream Interests

Early deposit mineral stream interests represent agreements relative to early stage development projects whereby Wheaton can choose not to proceed with the agreement once certain documentation has been received including, but not limited to, feasibility studies, environmental studies and impact assessment studies (please see Note 25 for more information). Once Wheaton has elected to proceed with the agreement, the carrying value of the stream will be transferred to Mineral Stream Interests.

18.1. Share Purchase Options

The Company has established an equity settled share purchase option plan whereby the Company's Board of Directors may, from time to time, grant options to employees or consultants. The maximum term of any share purchase option may be ten years, but generally options are granted with a term to expiry of five to seven years. The exercise price of an option is not less than the closing price on the TSX on the last trading day preceding the grant date. The vesting period of the options is determined at the discretion of the Company's Board of Directors at the time the options are granted, but generally vest over a period of two or three years.

Three and Nine Months Ended September 30, 2025 (US Dollars)

Each share purchase option converts into one common share of Wheaton on exercise. No amounts are paid or payable by the recipient on receipt of the option. The options do not carry rights to dividends or voting rights. Options may be exercised at any time from the date of vesting to the date of their expiry, subject to certain black-out periods.

The Company expenses the fair value of share purchase options that are expected to vest on a straight-line basis over the vesting period using the Black-Scholes option pricing model to estimate the fair value for each option at the date of grant. The Black-Scholes model was developed for use in estimating the fair value of traded options that have no vesting restrictions. The model requires the use of subjective assumptions, including expected share price volatility. Historical data has been considered in setting the assumptions. Expected volatility is determined by considering the trailing 36-month historic average share price volatility. The weighted average fair value of share purchase options granted and principal assumptions used in applying the Black-Scholes option pricing model are as follows:

18.2. Restricted Share Units ("RSUs")

The Company has established an RSU plan whereby RSUs will be issued to eligible employees or directors as determined by the Company's Board of Directors or the Company's Compensation Committee. RSUs give the holder the right to receive a specified number of common shares at the specified vesting date. RSUs generally vest over a period of two to three years. Compensation expense related to RSUs is recognized over the vesting period based upon the fair value of the Company's common shares on the grant date and the awards that are expected to vest. The fair value is calculated with reference to the closing price of the Company's common shares on the TSX on the business day prior to the date of grant.

RSU holders receive a cash payment based on the dividends paid on the Company's common shares in the event that the holder of a vested RSU has elected to defer the release of the RSU to a future date.

18.3. Long-Term Investment Revaluation Reserve

The Company's long-term investments in common shares (Note 15) are held for long-term strategic purposes and not for trading purposes. The Company has chosen to designate these long-term investments in common shares as financial assets with fair value adjustments being recorded as a component of OCI as it believes that this provides a more meaningful presentation for long-term strategic investments, rather than reflecting changes in fair value as a component of net earnings. As some of these long-term investments are denominated in Canadian dollars, changes in their fair value is affected by both the change in share price in addition to changes in the Cdn\$/US\$ exchange rate.

Where the fair value of a long-term investment in common shares held exceeds its tax cost, the Company recognizes a deferred income tax liability. To the extent that the value of the long-term investment subsequently declines, the deferred income tax liability is reduced. However, where the fair value of the long-term investment decreases below the tax cost, the Company does not recognize a deferred income tax asset on the unrealized capital loss unless it is probable that the Company will generate future capital gains that will offset the loss.

19. Share Based Compensation

The Company's share based compensation consists of share purchase options (Note 18.1), restricted share units (Note 18.2) and performance share units (Note 19.1). The accrued value of share purchase options and restricted share units are reflected as reserves in the shareholder's equity section of the Company's balance sheet while the accrued value associated with performance share units is reflected as an accrued liability.

19.1. Performance Share Units ("PSUs")

The Company has established a Performance Share Unit Plan ("the PSU plan") whereby PSUs will be issued to eligible employees as determined by the Company's Board of Directors or the Company's Compensation Committee. PSUs issued under the PSU plan entitle the holder to a cash payment at the end of a three year performance period equal to the number of PSUs granted, multiplied by a performance factor and multiplied by the fair market value of a Wheaton common share on the expiry of the performance period. The performance factor can range from 0% to 200% and is determined by comparing the Company's total shareholder return ("TSR") to those achieved by various peer companies and the price of gold and silver.

Compensation expense for the PSUs is recorded on a straight-line basis over the three year vesting period. The amount of compensation expense is adjusted at the end of each reporting period to reflect (i) the fair value of common shares; (ii) the number of PSUs anticipated to vest; and (iii) the anticipated performance factor.

20. Earnings per Share ("EPS") and Diluted Earnings per Share ("Diluted EPS")

Diluted earnings per share is calculated using the treasury method which assumes that outstanding share purchase options and warrants, with exercise prices that are lower than the average market price of the Company's common shares for the relevant period, are exercised and the proceeds are used to purchase shares of the Company at the average market price of the common shares for the relevant period.

Diluted EPS is calculated based on the following weighted average number of shares outstanding:

Three Months Ended

(in thousands) 2025 2024 2025 2024

Restricted share units 242 337 282 331
Diluted weighted average number of shares outstanding 454,768 454,302 454,625 454,037

There were no share purchase options excluded from the computation of diluted earnings per share as the exercise prices did not exceed the average market value of the common shares of Cdn\$134.73 (nine months - Cdn\$115.72) nor Cdn\$81.24 (nine months - Cdn\$71.84) for the comparable period in 2024.

Refundable Deposit – 777 PMPA

On August 8, 2012, the Company entered into a PMPA with Hudbay in respect to the 777 mine. Under the terms of the 777 PMPA, should the market value of gold and silver delivered to Wheaton through the initial 40 year term of the contract, net of the per ounce cash payment, be lower than the initial \$455 million upfront consideration, the Company is entitled to a refund of the difference (the "Refundable Deposit") at the conclusion of the 40 year term. On June 22, 2022, Hudbay announced that mining activities at the 777 mine have concluded after the reserves were depleted and closure activities have commenced. The balance of the Refundable Deposit is \$78 million.

At December 31, 2022, the Company derecognized the 777 PMPA and recognized a long-term receivable, with interest to be accreted on a quarterly basis until maturity which is August 8, 2052. The Company estimated that a credit facility with similar terms and conditions would have an interest rate of 8%.

  • 1) The production payment is measured as either a fixed amount per ounce of gold delivered, or as a percentage of the spot price of gold on the date of delivery. Contracts where the payment is a fixed amount per ounce of gold delivered are subject to an annual inflationary increase, with the exception of Sudbury. Additionally, should the prevailing market price for gold be lower than this fixed amount, the per ounce cash payment will be reduced to the prevailing market price, subject to an annual inflationary factor.
  • 2) Subject to an increase to \$550 per ounce of gold after the initial 40-year term.
  • 3) Under the terms of the San Dimas PMPA, the Company is entitled to an amount equal to 25% of the payable gold production plus an additional amount of gold equal to 25% of the payable silver production converted to gold at a fixed gold to silver exchange ratio of 70:1 from the San Dimas mine. If the average gold to silver price ratio decreases to less than 50:1 or increases to more than 90:1 for a period of 6 months or more, then the "70" shall be revised to "50" or "90", as the case may be, until such time as the average gold to silver price ratio is between 50:1 to 90:1 for a period of 6 months or more in which event the "70" shall be reinstated. Effective April 30, 2025, the fixed gold to silver exchange ratio was revised from 70:1 to 90:1.
  • 4) To be increased to 22% once the market value of all metals delivered to Wheaton, net of the per ounce cash payment, exceeds the initial upfront cash deposit.
  • 5) Under certain PMPAs, the Company's attributable gold percentage will be reduced once certain thresholds are achieved: a. Blackwater – reduced to 4% once the Company has received 464,000 ounces of gold.
  • b. Platreef reduced to 50% once the Company has received 218,750 ounces of gold, with a further reduction to 3.125% once the Company has received 428,300 ounces, at which point the per ounce cash payment increases to 80% of the spot price of gold. If certain thresholds are met, including if production through the Platreef project concentrator achieves 5.5 Mtpa, the 3.125% residual gold stream will terminate.
  • c. Marmato reduced to 5.25% once Wheaton has received 310,000 ounces of gold.
  • d. Santo Domingo reduced to 67% once the Company has received 285,000 ounces of gold.
  • e. El Domo reduced to 33% once the Company has received 145,000 ounces of gold.
  • f. Marathon reduced to 67% once the Company has received 150,000 ounces of gold.
  • g. Goose reduced to 1.44% once the Company has received 87,100 ounces of gold, with a further reduction to 1% once the Company has received 134,000 ounces.
  • h. Cangrejos reduced to 2.9% once the Company has received 469,000 ounces of gold. i. Curraghinalt – reduced to 1.5% once the Company has received 125,000 ounces of gold.
  • j. Koné reduced to 10.8% once the Company has received 400,000 ounces of gold, subject to adjustment if there are delays in deliveries relative to an agreed schedule, with a further reduction to 5.4% once the Company has received an additional 130,000 ounces of gold.
  • k. Kurmuk reduced to 4.8% once the Company has received 220,000 ounces of gold. During any period in which debt exceeding \$150 million ranks ahead of the gold stream, the stream percentage increases to 7.15% and decreases to 5.25% once the drop down threshold is reached.
  • l. Cotabambas reduced to 16.67% once the Company has received 90 million silver equivalent ounces.
  • 6) On October 21, 2024, the Company amended the Fenix PMPA. Under the original agreement, the Company was to acquire an amount of gold equal to 6% of the gold production until 90,000 ounces have been delivered, 4% of the gold production until the delivery of a further 140,000 ounces and 3.5% gold production thereafter for the life of mine. Under the revised agreement, the Company is entitled to purchase an additional 16% of payable gold production (22% in total) (subject to adjustment if there are delays in deliveries relative to an agreed schedule). Once Rio2 delivers the incremental 95,000 ounces (as adjusted), the stream reverts to the percentages and thresholds under the original Fenix PMPA (as described). Rio2 has a one-time option to terminate the requirement to deliver the incremental gold production from the end of 2027 until the end of 2029 by delivering 95,000 ounces (as adjusted) less previously delivered gold ounces, excluding those gold ounces which would have been delivered under the original Fenix PMPA.
  • 7) Under the Kudz Ze Kayah PMPA, the Company will be entitled to purchase staged percentages of produced gold ranging from 6.875% to 7.375% until 330,000 ounces of gold are produced and delivered, thereafter reducing to a range of 5.625% to 6.125% until a further 59,800 ounces of gold are produced and delivered, further reducing to

  • a range of 5% to 5.5% until a further 270,200 ounces of gold are produced and delivered for a total of 660,000 ounces of gold thereafter ranging between 6.25% and 6.75%.
  • 8) On February 27, 2024, the Company closed the Orion Purchase Agreement to acquire the Platreef and Kudz Ze Kayah PMPAs.
  • 9) Until October 23, 2029, there is a price adjustment mechanism under the Koné PMPA a. if the spot price of gold is less than \$2,100 per ounce, the Company will pay 20% of \$2,100 less 25% of the difference between \$2,100 and \$1,800, less 30% of the difference between \$1,800 and the spot price of gold; and
  • b. if the spot price is greater than \$2,700 per ounce, the Company will pay 25% of the difference between \$3,000 and \$2,700, plus 30% of the difference between the actual spot price of gold and \$3,000.

Tax Contingencies

Due to the size, complexity and nature of the Company's operations, various legal and tax matters are outstanding from time to time, including audits and disputes.

Under the terms of the settlement with the CRA of the transfer pricing dispute relating to the 2005 to 2010 taxation years (the "CRA Settlement"), income earned outside of Canada by the Company's foreign subsidiaries will not be subject to tax in Canada under transfer pricing rules. The CRA Settlement principles apply to all taxation years after 2010 subject to there being no material change in facts or change in law or jurisprudence. The CRA is not restricted under the terms of the CRA Settlement from issuing reassessments on some basis other than transfer pricing which could result in some or all of the income of the Company's foreign subsidiaries being subject to tax in Canada.

It is not known or determinable by the Company when any ongoing audits by CRA of international and domestic transactions will be completed, or whether reassessments will be issued, or the basis, quantum or timing of any such potential reassessments, and it is therefore not practicable for the Company to estimate the financial effect, if any, of any ongoing audits.

From time to time there may also be proposed legislative changes to law or outstanding legal actions that may have an impact on the current or prior periods, the outcome, applicability and impact of which is also not known or determinable by the Company.

General

By their nature, contingencies will only be resolved when one or more future events occur or fail to occur. The assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. If the Company is unable to resolve any of these matters favorably, there may be a material adverse impact on the Company's financial performance, cash flows or results of operations. In the event that the Company's estimate of the future resolution of any of the foregoing matters changes, the Company will recognize the effects of the change in its consolidated financial statements in the appropriate period relative to when such change occurs.

26. Segmented Information

Operating Segments

The Company's reportable operating segments, which are the components of the Company's business where discrete financial information is available and which are evaluated on a regular basis by the Company's Chief Executive Officer ("CEO"), who is the Company's chief operating decision maker, for the purpose of assessing performance, are summarized in the tables below:

Declaration of Dividend

Under the Company's dividend policy, the quarterly dividend is fixed at \$0.165 per common share for 2025. The declaration, timing, amount and payment of future dividends remain at the discretion of the Board of Directors.

On November 6, 2025, the Board of Directors declared a dividend in the amount of \$0.165 per common share, with this dividend being payable to shareholders of record on November 20, 2025 and is expected to be distributed on or about December 4, 2025. The Company has implemented a dividend reinvestment plan ("DRIP") whereby shareholders can elect to have dividends reinvested directly into additional Wheaton common shares based on the Average Market Price, as defined in the DRIP.

Acquisition of Spring Valley PMPA

On November 6, 2025, the Company entered into a PMPA (the "Spring Valley PMPA") with Waterton Gold Corp., a subsidiary of Waterton Gold LP ("Waterton Gold") in respect of its Spring Valley project located in Nevada, USA. Under the Spring Valley PMPA, the Company will purchase an amount of gold equal to 8% of the payable gold until 300,000 ounces have been delivered, after which the Company will purchase 6% of the payable gold for the life of the mine. Under the terms of the Spring Valley PMPA, the Company is committed to pay Waterton Gold total upfront cash payments of \$670 million, to be paid in installments as various conditions are satisfied. In addition, Wheaton will make ongoing payments for the gold ounces delivered equal to 20% of the spot price of gold until the value of the gold delivered, net of the production payment, is equal to the upfront consideration of \$670 million, at which point the production payment will increase to 22% of the spot price of gold. The Company also entered into a cost overrun facility (the "Facility") of up to \$150 million, accessible during an availability period commencing once the full upfront consideration has been paid under the Spring Valley PMPA. The Facility has a maturity date of three years following the first drawdown under the Facility.
